I am facing a problem with connecting to two different Redis databases in the scope of the same instance. My Redis configuration class looks like this:
package com.application.apigateway.intrastructure.cache;import java.time.Duration;import java.util.Properties;import lombok.extern.slf4j.Slf4j;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.context.annotation.PropertySource;import org.springframework.data.redis.connection.RedisConnectionFactory;import org.springframework.data.redis.connection.RedisPassword;import org.springframework.data.redis.connection.RedisStandaloneConfiguration;import org.springframework.data.redis.connection.jedis.JedisClientConfiguration;import org.springframework.data.redis.connection.jedis.JedisClientConfiguration.JedisClientConfigurationBuilder;import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;import org.springframework.data.redis.core.RedisTemplate;@Configuration@PropertySource("classpath:redis.properties")@Slf4jpublic class RedisConfiguration { private static final String REDIS_PROPERTIES = "redis.properties"; private final Properties redisProperties = readConfigurationFile(REDIS_PROPERTIES); @Value("${redis.host}") private String host; @Value("${redis.port}") private int port; @Value("${redis.password}") private String password; @Value("${redis.timeout}") private String timeout; @Bean(name = "redisUserConnectionFactory") public JedisConnectionFactory redisUserConnectionFactory() { RedisStandaloneConfiguration redisConfiguration = new RedisStandaloneConfiguration(); String userDb = getProperty(redisProperties, "redis.user.cache.database"); redisConfiguration.setHostName(host); redisConfiguration.setPort(port); redisConfiguration.setDatabase(Integer.parseInt(userDb)); redisConfiguration.setPassword(RedisPassword.of(password)); JedisClientConfigurationBuilder jedisClientConfiguration = JedisClientConfiguration.builder(); jedisClientConfiguration.connectTimeout(Duration.ofMillis(Long.parseLong(timeout))); log.info("Connected to Redis host: {}, port: {}, database: {}", redisConfiguration.getHostName(), redisConfiguration.getPort(), redisConfiguration.getDatabase()); return new JedisConnectionFactory(redisConfiguration, jedisClientConfiguration.build()); } @Bean(name = "userRedisTemplate") public RedisTemplate<String, Object> userRedisTemplate( @Qualifier(value = "redisUserConnectionFactory") RedisConnectionFactory redisConnectionFactory) { RedisTemplate<String, Object> template = new RedisTemplate<>(); template.setConnectionFactory(redisConnectionFactory); return template; } @Bean(name = "redisRegistrationTokenConnectionFactory") public JedisConnectionFactory redisRegistrationTokenConnectionFactory() { RedisStandaloneConfiguration redisConfiguration = new RedisStandaloneConfiguration(); String registrationTokenDb = getProperty(redisProperties, "redis.registration.token.cache.database"); redisConfiguration.setHostName(host); redisConfiguration.setPort(port); redisConfiguration.setDatabase(Integer.parseInt(registrationTokenDb)); redisConfiguration.setPassword(RedisPassword.of(password)); JedisClientConfigurationBuilder jedisClientConfiguration = JedisClientConfiguration.builder(); jedisClientConfiguration.connectTimeout(Duration.ofMillis(Long.parseLong(timeout))); log.info("Connected to Redis host: {}, port: {}, database: {}", redisConfiguration.getHostName(), redisConfiguration.getPort(), redisConfiguration.getDatabase()); return new JedisConnectionFactory(redisConfiguration, jedisClientConfiguration.build()); } @Bean(name = "registrationTokenRedisTemplate") public RedisTemplate<String, Object> registrationTokenRedisTemplate( @Qualifier(value = "redisRegistrationTokenConnectionFactory") RedisConnectionFactory redisConnectionFactory) { RedisTemplate<String, Object> template = new RedisTemplate<>(); template.setConnectionFactory(redisConnectionFactory); return template; }}and
pom.xml looks like:

the application starts I am receiving:
***************************APPLICATION FAILED TO START***************************Description:A component required a bean named 'redisTemplate' that could not be found.Action:Consider defining a bean named 'redisTemplate' in your configuration.I am a little bit confused because I created two separated RestTemplate beans and it still doesn't bring a desirable effect. I will be grateful for suggestions on how to fix this problem.
